Abstract
A method for computing includes executing a program, including multiple cacheable lines of executable code, on a processor having a software-managed cache. A run-time cache management routine running on the processor is used to assemble a profile of inter-line jumps occurring in the software-managed cache while executing the program. Based on the profile, an optimized layout of the lines in the code is computed, and the lines of the program are re-ordered in accordance with the optimized layout while continuing to execute the program.
